摘要:
以硅藻土为主要原料,添加适量烧结助剂,采用干式研磨、滚球成型和高温煅烧工艺,制备硅藻土基多孔陶粒。硅藻土基多孔陶粒单独吸附1 L 10 mg/L对苯醌时的最佳用量为10 g,其去除率为9.55%。单独采用Fenton法降解对苯醌时,FeSO4(50 mmol/L)的最佳投加量为8 mL,H2O2(100 mmol/L)为40 mL,最佳pH值为5,此时去除率为59.89%。将硅藻土基多孔陶粒与Fenton法联用,结果表明,二者有明显的协同作用,去除率增至70.29%,较单独采用硅藻土基多孔陶粒增加了6.36倍,较单独采用Fenton法增加了17.4%。同时研究了对苯醌在硅藻土基多孔陶粒与Fenton法联用条件下的吸附动力学行为。对苯醌在硅藻土基多孔陶粒与Fenton法联用条件下吸附速率加快,且吸附去除大部分发生在反应初始阶段60 min内,Elovich和双常数动力学模型能较好地对试验数据进行非线性拟合。
